Hi! Please excuse bringing up a topic as old as this, again. Only bringing up half, actually.

At least on http://download.blender.org/source/ these two appear as consecutive releases. While doing digital cleaning over here I ran into my patches to make ancient Blender compile again for Gentoo logo rendering. I have streamlined those into ebuilds and a dedicated overlay https://github.com/gentoo/blender-gentoo-logo-overlay and filled the void in the Gentoo wiki https://wiki.gentoo.org/wiki/Project:Artwork/Artwork#The_blue_.22g.22_logo with a few words and pointers. The ebuilds are: dev-lang/python/ python-2.2-r8.ebuild media-gfx/blender/ blender-2.26.ebuild blender-2.31a.ebuild So whoever needs to render Blender files from 2003 again at some point should find working ebuilds to do that. Feel free to join keeping them in good installable shape. Thanks and best, Sebastian

My experience modelling in Blender is zero, so it's hard to tell to right now me. From a few cases of remaking vector art from raster images in Inkscape, I can imagine that it's difficult to get very close in Blender too, if not more. I hope to have a better answer soon. Best, Sebastian This may be a nice opportunity to reach out to the blender community and ask for assistance and/or training.

Bisecting involves fixing compilation for each version. I stopped getting 2.30 to compile because it seemed to take forever (longer than fixing 2.26, 2.37a and 2.40 together) and two people had their hands on a port of the logo to Blender 2.57 by then, one of them still has. It's too early to give details. What I can say is that personally I would want a very close match in case of a Blender-based replacement, closer than what I have seen so far. It still seems possible though. Best, Sebastian

Of the three variants trying to match the Blender version that I have seen so far, none is a replacement of equal quality on the bling scale to my impression. They feel like tradeoffs, not like the real thing. Maybe they try to come too close to the ray-traced rendering, but I'm not sure if I really want to propose a different direction either. I think such a variant would be much more portable and reproducible than blender files. What I dislike about the idea of moving to a new logo is that we would give up part of our culture just because we were unable to move it from past to present to future. Imagine this dialog: A: Hey guys, I noticed you have a new logo? B: Yeah, blender rendering changed - so we dropped it. I don't really want to be B in that dialog. I see the pragmatic aspect of moving to SVG but it also has the taste of giving up to me. To vercome that taste, a very strong replacement would be needed. If we replace the Blender g we may also need a substitute for the red-white Blender gentoo as seen at http://sources.gentoo.org/cgi-bin/viewvc.cgi/*docroot*/images/gentoo-new.gif if just for the sake of consistency. I am wondering what effect the Blender nature of a logo does have on the capability and will of people to create fan art based on it compared to an SVG version. It seems like there is only a handful of 3D Gentoo wallpapers but does that mean it would have been more with an SVG version, instead? On what levels could SVG work as a catalyst? If we ported the logo to Blender 2.57 now: what can we do to not be running after Blender rendering changes for all time or to reduce their impact on us? Is this a natural cost or an evil one? Just my 2 cents. Best, Sebastian

Imagine this dialog: A: Hey guys, I noticed you have a new logo? B: Yeah, blender rendering changed - so we dropped it. Well, the concept is to have the same logo but in new format. Of course, that would require some of professional work to ensure best-match rendering if even possible. And I don't think it's really giving up. It's just moving to the future, putting back good, ol' things in the museum. However, it'd be still best to fix it.

It seems like there is only a handful of 3D Gentoo wallpapers but does that mean it would have been more with an SVG version, instead? On what levels could SVG work as a catalyst? As I see the concept of a logo, it is bound to a pretty strict rendering. It's fun to have it in 3D but I'm not sure if, say, rotating it or changing lighting would still make it the same logo. -- Best regards, Michał Górny signature.asc Description: PGP signature
